My mother and I are also looking for the name "Nyas". The only connection that we have at the moment is there was a family that moved to Newcastle-Upon-Tyne, England, from...we believe....south africa?!.
David Adolphus Nyas, father to five children. Married Janet Cummins. Eldest daughter Sarah, born 1896, 4th August.
